Britain's Duchess Catherine's mother is trained to deliver babies.
Carole Middleton underwent emergency midwife training at British Airways' Cranebank centre in west London in 1976, while she was working as an air stewardess, to learn how to help women in labour just in case any passengers entered the phase while onboard.
In an extract from Marcia Moody's book about Duchess Catherine - who was previous known as Kate Middleton before her and Prince William's nuptials - 'Kate: A Biography', the former royal correspondent described Carole's training as "an antiquated finishing school".
She added: "They were taught how to be good listeners, how to maintain good eye contact and always have a smile on their face.
"Many people commented on how composed the Middletons were at the royal wedding and it struck me that Carole's training provided exactly the right sort of skillset you might need to be a member of the Royal Family.
"I'm sure part of it has rubbed off on Kate."
In a break from royal tradition, the Duke and Duchess of Cambridge's baby, who is due on Saturday (13.07.13), will spend the first six weeks of his or her life with Catherine at her parents' Carole and Michael Middleton's £4.85million Georgian manor in Berkshire, south east England.
The duchess has previously said she will feel "safest and most secure" at her parents' abode.
